Hello,

I am planning to dump my disk to newer disk with different partition.
Which method I have to handle for best result, Whether tar, dd, cpio,
ufsdump..... and how to do it.

Thanks,

Hi,

If you are dumping to a disk with different partitions, not sure that
dd is the best method - I'd use ufsdump or flarcreate (uses cpio).

anyway here are some examples that may help you

dd (when target disk on same bus and is at least big as source disk):

Bring system into single user mode (its better):
Check the controller and target numbers (in this example I'm copying
c1t0d0 to c1t1d0)

# dd if=/dev/rdsk/c1t0d0s2 of=/dev/rdsk/c1t1d0s2 bs=64k


Flarcreate:

# flarcreate -n "image name" -c -S -R / -x /var/tmp
/var/tmp/flash_image.flar


-c = compression
-S = don't calculate the size which makes it faster! (only
recommended if you are sure you have enough space in available in
/var/tmp)
-x = directory to exclude from the image (can temporarily move other
files in here that you don't really need to copy such as database
dumps etc.)

Once you have the flash image, ftp it to the network you want and make
it available on an NFS shared directory. Then install solaris on the
new CTP using "boot cdrom - w" to access the installer program,
choose all the normal solaris build options and when asked; choose
"Flash install" and input the location of the NFS directory
containing the image. The advantage of this method allows you to make
multiple clones, and you don't need to edit host names and IP
addresses etc.

Hello Trev,

We are have 2 nodes and some shared disk. We have to install according
to the projects specification. As the projects will change with in few
months we have to go for the fresh installation for the second project.
If the first project comes back for some maintance or testing we have
to go from the scratch for installation. Is there is any tools for
Fast System Recovery? . Please let me know about this.

Thanks,

Either flarcreate, or live upgrade (lu). Check the man pages.
